Remove unused includes of StyleInheritedData.

Before we can generate StyleInheritedData, we must first remove any
references to it outside of ComputedStyle. A lot of files include the
header file for StyleInheritedData, but do not use it. This will cause
a compile error when we remove the file to generate it instead.

This patch removes the unused includes, as lead-up to generating
StyleInheritedData.
